Apparatus for cooling a battery

Abstract

An apparatus for cooling a battery includes a cooling plate having a cooling channel, and a spacer element disposed in the cooling channel. Also described is a method for producing the apparatus, a battery which includes the apparatus, and a vehicle which includes the apparatus.

What is claimed is: 
     
         1 . An apparatus for cooling a battery, said apparatus comprising:
 a cooling plate defining at least a portion of a cooling channel, and   a spacer element disposed in the cooling channel.   
     
     
         2 . The apparatus according to  claim 1 , wherein at least a portion of the spacer element extends to an edge of the cooling channel. 
     
     
         3 . The apparatus according to  claim 1 , wherein the apparatus comprises two of the cooling plates between which a compression element is disposed, wherein the spacer element of the respective cooling plate is disposed on a side of the cooling plates facing away from the compression element. 
     
     
         4 . The apparatus according to  claim 3 , wherein the spacer element of one of the two cooling plates is disposed offset from the spacer element of the other of the two cooling plates. 
     
     
         5 . The apparatus according to  claim 1 , wherein the spacer element comprises an undercut that extends substantially along the cooling channel. 
     
     
         6 . A battery comprising the apparatus according to  claim 1 . 
     
     
         7 . A vehicle comprising the battery of  claim 6 . 
     
     
         8 . A method for producing an apparatus for cooling a battery, said apparatus comprising (a) two cooling plates each defining (i) at least a portion of a cooling channel and (ii) a spacer element disposed in the respective cooling channel, and (b) a compression element disposed between the two cooling plates,
 wherein said method comprises, for each cooling plate, producing the spacer element by rolling and/or roll forming the cooling plate.   
     
     
         9 . The method according to  claim 8 , wherein the compression element is produced by rolling and/or folding with a mold which corresponds to a shape of a side of the cooling plate facing away from the spacer element, and wherein the compression element is inserted between two cooling plates. 
     
     
         10 . The method according to  claim 9 , wherein the apparatus is cut to length or punched.
